Load Base64-encoded X.509 Certificate (.cer)

See more Certificates Examples

Loads a digital certificate from a base64 encoded DER X.509 Certificate (.cer, .crt) and fetches information about the cert. C++

#include <CkCert.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkCert cert;

    // LoadFromFile will load virtually any certificate format file.
    // It will auto-recognize the format and load appropiately.
    // A base64-encoded DER X.509 certificate file
    // contains the binary DER in base64 encoded form.
    // Therefore, it is a text file that will begin like this:
    // -----BEGIN CERTIFICATE-----
    // MIIFbjCCBFagAwIBAgIGdDPNv/L0MA0GCSqGSIb3DQEBBQUAMIHKMQswCQYDVQQG
    // EwJVUzEQMA4GA1UECBMHQXJpem9uYTETMBEGA1UEBxMKU2NvdHRzZGFsZTEaMBgG
    // ...

    success = cert.LoadFromFile("/Users/chilkat/testData/cer/chilkat_base64.cer");
    if (success != true) {
        std::cout << cert.lastErrorText() << "\r\n";
        return;
    }

    // DN = "Distinguished Name"
    std::cout << "SubjectDN:" << cert.subjectDN() << "\r\n";

    std::cout << "Common Name:" << cert.subjectCN() << "\r\n";
    std::cout << "Issuer Common Name:" << cert.issuerCN() << "\r\n";

    std::cout << "Serial Number:" << cert.serialNumber() << "\r\n";
